- EuMC: Advanced Filter Design Using Cross-Coupled Networks . . .
Abstract — A new class of cross-coupled networks is presented for the advanced design of microwave filters By including nodes for higher lower-order mode resonances, a broadband model is obtained which partly eliminates the narrowband restrictions found in current coupling matrix approaches Several bandpass filter examples for WR75 waveguide applications are presented It is demonstrated
- Design of Dual-Band Waveguide Transformers - UVic. ca
The theory and design of transmission-line and waveguide impedance transformers are well documented and understood [1], [2] Many of the underlying principles found their way into computer-aided synthesis and design algorithms, e g [3], but only little work on transformers focused on the dual-band nature used, for example, in antenna feeds of modern communication systems such as satellite and
- Rigorous Design of Sidewall Aperture Couplers - UVic. ca
ABSTRACT The rigorous field theory CAD of rectangular wave-guide sidewall aperture couplers is introduced which are coupled by rectangular apertures of different size Based on the rectangular waveguide T–junction and the double–step discontinuity key–building block modal S–matrices which are calculated by the mode-matching method, the design takes rigorously into account both the
- Associations between age, red cell distribution width and 180 . . .
Objective The aim of this study was to investigate the correlation between age, red cell distribution width (RDW) levels, and 180-day and 1-year mortality in giant cell arteritis (GCA) patients hospitalized or admitted to the ICU
- Site Characterisation, Deep Basement Support, Construction . . .
Abstract Deep basement construction is charac-terised by a deformation challenge for the excava-tion pit and adjacent structures Basement construc-tion is an unavoidable problem in urban areas A case is found in a Triumph Unit building block project, where a 14 m basement will be constructed near the existing structures Conducting a site survey engi-neering analysis before the deep basement

INTRODUCTION H-plane inductive-iris waveguide filters are frequently employed in modern communication systems Owing to their ease of fabrication and simplicity in numerical modeling, they have been proven especially useful in front ends and di multiplexer applications, e g [1], [2] Recent requirements in a densely populated frequency spectrum demand that many filter components be equipped
- An Integrated T-Septum Waveguide Diplexer for Compact Front . . .
ABSTRACT This paper introduces a new T-septum waveguide diplexer for compact integrated front-end applications in mod-ern communication systems The 8 74 10 14 GHz X-band design for four-percent channel bandwidths is one of the most compact waveguide diplexers ever presented The size reduc-tion is predominantly achieved by utilizing T-septum filter tech-nology which reduces the dimensions of
